How to Fix Antminer E9 Keeps Restarting


If you’re experiencing issues with your Antminer E9, such as it constantly restarting, it can be frustrating and affect your mining efficiency. In this blog post, we’ll provide some steps to fix the Antminer E9 restarting issue.


a. The power supply is unstable. When the miner is working, the output power current of the hash board can reach 200-300A, and the output power of the liquid-cooled miner is higher. When the output power fluctuates wildly, it will cause the miner to restart. In this case, you can try to replace the power supply of the Antminer E9. Antminer E9 uses APW12 PSU.

b. The control board is damaged. The control board is the center of the miner and is equivalent to a microcomputer. When the control board is abnormal, it will also cause the miner to restart. Generally, it can be solved by restoring the miner’s factory settings or flashing the firmware of the control board with an SD card; if the fault still cannot be solved, you can try to replace the Antminer E9 control board.

c. The chip is unstable. Generally, the fault can be found by querying the miner log. Then, find the faulty hash board, use the test fixture to detect the faulty BM1746 chip, and replace the faulty chip.

d. The network is unstable. Network instability also has a certain probability of causing miners to restart. Generally, you can try to replace the network cable or network cable connector, and then perform a local inspection.

e. Update the Antminer E9 firmware: Check if there are any firmware updates available for your Antminer E9 and update if necessary.

f. Check the temperature: Overheating can cause your Antminer E9 to restart. Check the temperature of the device and make sure it is within the recommended range.
